Network Production Engineer

The Infrastructure Network Engineering (INE) team within Core Networking designs and owns the datacenter management networks that underpin Meta's entire production IP network. Our products include out-of-band (OOB) management networks, disaster recovery infrastructure, passive optical networks (PON), and facilities networking (FacNet) — present in every datahall, every network rack, and every compute rack across Meta's global fleet.

INE is a design team with full product lifecycle ownership. You will drive network products from requirements and RFC through design specification, proof-of-concept lab validation, and production operational accountability. Our portfolio spans more device roles and vendors than almost any other networking team at Meta — backbone, server, VPN, TOR, aggregation, MACsec, and more. If you want to solve scaling problems across a broad technology landscape rather than specializing in a single protocol domain, this is the role.

As a Production Engineer in the network organization at Meta, you will combine the skills of a software and network engineer. You will use data analysis to influence design decisions and leverage automation to achieve the scale and velocity that Meta's AI-era data center growth demands.

Responsibilities

• Design, deploy, and maintain multi-vendor, multi-protocol infrastructure networks (OOB, PON, FacNet, DR) across every Meta datacenter and POP location
• Own the full product lifecycle — from requirements gathering and RFC through design specification, POC lab validation, configuration artifacts, and production operational accountability
• Write and review code, develop automation for the network deployment, configuration management, and release engineering workflow processes
• Drive New Platform Introduction (NPI) from concept through lab validation to production handoff, collaborating with production engineering teams for productionization and delivery teams for delivery at scale
• Develop audits, health checks, and monitoring to ensure network health and safe change management across the fleet
• Maintain technical relationships with networking vendors (Juniper, Cisco, Arista, Ciena), drive roadmap alignment, and lead hardware evaluations
• Define SLAs, implement metric collection and reporting for the network products you own
• Proactively identify cross-team gaps across the product portfolio and drive resolution through cross-functional collaboration
• Together with the rest of your team, share an oncall rotation and serve as an escalation contact for service incidents

Minimum Qualifications

• Bachelor\'s degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience
• 6 years of work experience in network engineering, with emphasis on network design or architecture (not purely operations)
• 4+ years of work experience in coding in higher-level languages (e.g., Python, Go, C++), applied to network automation or infrastructure tooling
• Experience in developing and understanding network device configuration for multiple vendors (Juniper, Cisco, Arista, Ciena, or an equivalent)
• Protocol experience in one or more of BGP, OSPF, or ISIS — understanding of typical configurations and performance optimizations
• Experience developing software using AI models or integrating AI tools into engineering workflows
• Bachelor\'s degree in Computer Science, Computer Engineering, a relevant technical field, or equivalent practical experience

Preferred Qualifications

• Experience with hardware evaluation, vendor management, and influencing network product roadmaps through cross-functional collaboration
• Experience in configuration and maintenance of network management systems or applications such as authentication servers (RADIUS/TACACS), logging infrastructure, or collection systems (SNMP/NETCONF/gNMI)
• Experience with IPSec for site-to-site or remote access VPNs
• Experience with XGS-PON or passive optical network technologies. Experience with out-of-band management networks, disaster recovery network infrastructure, or facility networking
• 2+ years of experience in network design or architecture, with product ownership from concept through production
• Experience adhering to and implementing responsible, ethical AI practices (e.g., risk assessment, bias mitigation, quality and accuracy reviews)
• Expert knowledge of TCP/IP and IPv6
• Demonstrated ongoing AI skill development (e.g., prompt/context engineering, agent orchestration) and staying current with emerging AI technologies
• Demonstrated ability to integrate AI tools to optimize/redesign workflows and drive measurable impact (e.g., efficiency gains, quality improvements)
